I COOLING NOZZLE FOR TEMPERING HOLLOW GLASSWARE Filed-Nov. 25, 1939 Patented Jan. 26, 1943 COOLING NOZZLE FOR TEMPERING HOLLOW GLASSWARE William E. Aksomitas, Hartford, Conn., assignor .to Hartford-Empire Company, Hartford, Conn.,

a corporation of Delaware v Application November 25, 1939, Serial No. 306,125

(Cl. 49-45l 5 Claims.

The present invention relates to tempering hollow glassware, such as bottles and jars, each of which has a single restricted opening.

It provides a novel internal cooling nozzle adapted to enter the ware through the opening and to apply a cooling medium, as for example, air or steam, to the internal walls in a plurality of jets and to remove the spent medium through a plurality of spaced exhaust openings.

The nozzle and the ware may be rotated relatively to each other so that the cooling .iets scan the walls. The exhaust openings in the nozzle may be so located that they follow the jets in adjacent planes and thus remove the spent gases without objectionable interference with the cooling jets,

The nozzle may be employed with any suitable apparatus, as for example, that disclosed in the application of Thomas D. Green, Serial No. 306,085 filed, November 25, 1939, the same date as this application, by which the ware while being cooled, may be held by tongs and locked in proper alignment by a member contacting the rim of the Ware. The nozzle of my invention may be provided to handle all exhaust gases or it may be arranged to carry only a part thereof, the remainder passing out of the ware around the nozzle.

My novel method of tempering glassware of the types mentioned comprises blowing jets of cooling medium at a plurality of levels against the interior walls of the ware and removing the spent gases from the ware at a plurality of levels.

Other features of my invention will be apparent from the following specification and drawing of which:

Figure 1 is aview in vertical section of one form of nozzle of my invention shown in association with a narrow neck bottle held by tongs and a locking member;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a view in elevation of a combined tong and nozzle mechanism with which the nozzle of Figs. l and 2 may be employed.

The apparatus of Fig. 3 is substantially the same as that shown in the aforesaid Green application, and as shown comprises a tubular casing II mounted on a bracket I2. Within the casing I land extending above and below it is a tubular member I3 which carries a sleeve I4, providing a mounting for tongs I5. annular disk-like form is mounted on a lower end of the member yI3 for contact at its lower surface with the mouth end of an article of hollow glassware which has been. gripped by the tongs I5.

The member I3 is mounted for rotation, when def' A locking member I6 of sired, through a beveled gear I8 and connection shown, by a motor I9.

The nozzle 20 is removably carried by a pair of concentric tubular members 2| spaced apart but secured together and within the member I3, above which they extend to carry beveled gear 22 by which the nozzle may beA rotated about its axis. The nozzle may be moved vertically relatively to an article of ware gripped by the tongs, by means -including lever 23 and link 24 connected to sleeve 25 on the member 2I between collars 26 and 2l.

An external cooling device is indicated at 28 which may be rotated through sprocket 29. A

The locking member I6 may, if desired, be provided with seri-ations 3D in its lower surface to provide exits of selected size for a predetermined portion of the spent cooling medium which passes through the restricted passage 3| between the nozzle and the wall of the neck iinish and scrubs the internal wall of the neck of the bottle. Such an arrangement may provide for adequate cooling without excessive chilling of the neck.

The nozzle 2i)`comprises an outer tube 32 se,- cured at its lower end to an inner tube 33, the space between the two providing an inlet passage 34 for the cooling medium. An exhaust passage is provided within the tube 33. Thevouter tube is provided with a series of spaced jet holes 35, the sizes of the holes and their spacing being selected to give the desired jet pattern. l The internal tube 33 communicates through passages 3B with a sem ries of exhaust holes 3l in the outer tube 32. These exhaust holes are preferably spaced from the holes 35 about the periphery of the tube and are preferably located in horizontal planes between the planes of the holes 35. At the lower end of the nozzle are provided jet holes 38 directed toward various portions of the bottom and/or lower corners of the ware. The lower end of the inner tube 33 is open to provide an exhaust hole adjacent the bottom of the ware. Cooling medium under pressuremay be supplied to the nozzle from a source (not'shown) through pipe 39, and the space between the members 2I and the spent gases may exhaust through the inner of the members 2I and exhaust pipe 40.

As shown in Figs. 1 and 2, the nozzle is provided withia single vertical row of inlets 35 and a single vertical row of outlets 31. If desired, these rows may be multiplied to give a better scanning effect and the exhaust holes 31 may be located in the same planes as the jet holes or in planes between the jets. Ordinarily the exhaust holes provided are somewhat larger than the in-l let holes and they may be more'or less in number as desired. v

In the use of the nozzle shown in Fig. 1, I contemplate that the ware and the nozzle be rotated relatively one to the other to cause the jets from the holes 35 and 38 to scan the surface of the walls. In general the jets from holes 35 are normal to the side walls. One or more of them may be directed at different angles. After contact with the wall the medium which has been heated by contact with the wall tends to return between the planes of the jets and generally in the planes of the exhaust holes by which it is rapidly and eiliciently removed from the ware. Similarly the provisions of the holes 38 and the bottom exhaust hole tend to remove the heated gases in paths which'provide little, if any, interference with the oncoming cooling jets.

The cooling jets are thus made more eicient A than they would be were they forced to pass through streams of exhausting gases moving transversely of the jets toward the opening in the were. Various modifications of my invention may be made without departing from the invention as expressed in the accompanying claims.
